Incredible retro-futuristic monuments from former Yugoslavia (now Croatia, Serbia, Slovenia, Bosnia and Herzegovina, etc.). The tricky engineering structures were commissioned by former Yugoslavian president Josip Broz Tito in the 1960s and '70s to commemorate sites where WWII battles took place (Tjentište, Kozara, Kadinjača), and where concentration camps once stood (Jasenovac, Niš).

The monuments were designed to convey the confidence and strength of the Socialist Republic. Sculptors include Dušan Džamonja, Vojin Bakić, Miodrag Živković, Jordan and Iskra Grabul, to name a few. Bogdan Bogdanović and Gradimir Medaković were the architects.

In the 1980s, the monuments attracted millions of visitors each year, especially young pioneers for their "patriotic education." After the Republic dissolved in the early 1990s, they were completely abandoned and their symbolic meanings faded away.
